Self-organization

Hierarchical self-assembly of block copolymers has been achieved by two steps of sequential ordering processes, consisting of self-organized micropatterning from a dewetting block polymer solution and thermal annealing. The self-organized micropattern induces the spontaneous alignment of self-assembled lamellae (see figure), which is successfully applied for a lithography-free, ultra-large-scale nanopatterning.
